Abstract (en)
A composition of matter comprising: (a) 5 to 40 weight percent inclusive of a low molecular weight ethylene resin made using a titanium catalyst system said resin having a density greater than 0.955 grams per cubic centimeter, a melt index greater than 25 grams per 10 minutes, and a heterogeneity index between 2 and 8 inclusive; and (b) 60 to 95 weight percent inclusive of a high molecular weight ethylene copolymer resin made using a chromium catalyst system said resin having a density of at least 0.93 grams per cubic centimeter, a high load melt index between 1.5 and 15 grams per 10 minutes, and a heterogeneity index between 6 and 100 inclusive; wherein said composition of matter has a melt index greater than 0.05 grams per 10 minutes.
